LEATHER-CUTTING DIE.

. Application filed March 30, 1926.

This invention relates to leather cutting dies and it is an object of the invention to provide a device of this kind wherein the ,strips or thongs as cut from the hide may be readily trimmed to provide a predetermined cross sectional configuration and in a manner whereby is substantially eliminated the liability of the finished strip or belt being-uneven or having nicked or cut out places in its surface. I

In order to keep a leather belt or strap strong, the grain of the leather on the surface of the hide must be preserved or retained. It is another object of the invention to provide a die having means whereby such grain of the leather is preserved during the desired cutting operation.

The invention consists in the details of construction and in the combination and arrangement of the several .parts of my improved leather cutting die whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use. as will be hereinafter more fully set forth.

The novelfeatures of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawing, wherein:-

Figure 1 is a view partly in section and partly in elevation illustrating a die constructed in accordance with an embodimentof my invention and in applied position with respect to a leather strip or thong;

Figure 2 is a sectional view taken substantially on the line 22 of Figure 1;

Figure 3 is a view similar to Figure 1 illustrating a further embodiment of my invention;

Figure 4 is a view in elevation of the receiving end of the die as illustrated in Figure 3, th leather strip or thong being omitted;

Figure 5 is a view in top plan of a still further form of my improved die, the coacting leather strip or thong being shown in fragment;

Figure. 6 is a view in elevation of the receiving end of the die illustrated in Figure 5 with the leather strip or thong omitted;

Figure 7 is a view in side elevation of another embodiment of my die with the 00- Serial No. 93.584.

acting leather strip or thong s own in fragment;

Figure 8 1s a view 111 elevation of the receiving end of the die illustrated in Figure Figure 9 is a view in ,top plan of the structure illustrated in Figure 7.

As particularly illustrated'in Figures 1 and 2 of the drawings, 1'denotes an elongated tubular member of requisite dimensions and which has its bore 2 gradually increased in diameter from its receiving end to its delivery end. The end edge of the member 1 at its receiving end constitutes a knife edge 3 except for the outwardly disposed lip or extension 4 which is relatively broad and has its free extremity slightly upturned, as at 5.

lVhen a leather stripor thong is first out from a hide it is rectangular in cross section. The die illustrated in Figures l and 2 is of a type to produce a leather strap or belt circular in cross section and which desired configuration is given to the strip or thong by the cutting edge 3 as said strip or thong passes through the member 1.

In order to keep the resultant strap or belt strong, the grain of the leather from the top surface of the hide should be preserved or retained.

The extension or lip 4 serves as a guide to facilitate the passage of the strip or thong into the member 1 and provides means whereby the top or grain of the leather is retained to an extent equal to the width of said extension or lip.

In practice, the' leather strip or thong as it is received within the member 1 is preferably disposed on a downward curvature with the extension or lip 4 uppermost.

By having the bore 2 of the member 1 gradually increased in diameter from its receiving end to its discharge end allowance is made for easement of the cutportion of the strip or thong as it passes through the die or member 1.

The extension or lip 4, or guide member as it may be termed, prevents digging into the strip or thong as it enters the die and thereby eliminates the liability of nicking or cutting of the leather. It is to be understood that the die 1 is to be placed in a well known manner upon a conventional machine or holder employed in work of this character.

In the embodiment of my invention as illustrated in Figures 3 and 4, the die 1 is provided at its receiving end with the diametrically opposed guide members 4 each operating for the same purposes as the extension or lip 4 hereinbefore referred to.

In the embodiment of my invention illustrated in Figures5 and 6,thebore 2 of the die 1 is substantially oval in cross section and the extension or lip 4 is arranged at a major side of such bore.

In Figures 7, 8 and 9, I illustrate a form of my invention wherein the bore 2' of the die 1 has a cross sectional configuration known in the trade as a V out, the lip or extension 4* being preferably at the top of the die during a Working operation.

From the foregoing description it is thought to be obvious that a leather cutting die constructed in accordance with my in? vention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it Will also be obvious that my invention'is susceptible of some change and modification Without departing from the principles and spirit thereof and for this realike comprising an elongated tubular member having an outstanding longitudinally extending projection at one end, the remainder of the end constituting a cutting ed 'e.

In testimony whereof I hereunto affix my signature.
